Improvement in lamps



CHARLES D. MAGQUEEN, OF PHILADELPHIA, PENNSYLVANIA.

Letters Patent No. 111,360, dated January 31, 1871.

I IMPROVEMENT IN LAMPS.

The Schedule referred to ln these Letters Patent and making part of the same.

To allivlwm it may concern Be itknown that I, CHARLES D. MAOQUEEN, of the city and county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Lamp-Stands; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawing and to the letters of reference marked thereon.

The object of my invention is to provide a cheap, simple, and durable stand for supporting a lamp at any height desired.

The stand consists of a base-piece and an adj ustable rod or tube, provided with a socket for holding the lamp.-

Figure 1 is an elevation of my improvement in lamp-stands.

Figure 2 is a vertical section of the socket.

Figure 3 is a view of the socket, showing it applied to a walhbracket or gas-fixture.

To enable those skilled in the art to make my invention, I will now proceed to describe it;

The base-piece B of the istand s made of any material, and in auy ornameutal design, in theucenter of which is secured a vertical tube, T, with the uppereud somewhat enlarged, and provided with a set-screw, S, for holding the rod or tube R, which slides within it,,extcnded to any heightdesired.

The rod or tube R bears o'n its upper end a cylindrical-shaped socket, 1), into which the lower end of the lamp is inserted, theattachment being made by means of a screw-threml formed on the rod or tube, and a correspondingfemale screw-thread formed in the center and lower part of the socket, thus allowing it' to be taken of and applied to a wall-bracket or gas-fixture for retaining the-lamp, as shown at fig. 3.

The opening made in the lower part vof the socket D, fig. 2, for the reception of the upper end of the rod or tube R, extends up into a circular boss, 1),.

formed in the interior, and on which the bottom part of the lamp rests when inserted, thus allowing a space in the lower part of the socket into which any oildrippi-ng down on the outside of the lamp may accumulate. I

The annular lamp L has secured on the upper surface of the oil vessel three uprights, E E E, made with recesses in the upper ends, into which the lower edge of the shade rests, they being made of sufiicient height to bring the edge of the shade on a line with the lower part of the burner.

The socket is made to fit loosely around the cylinder O of the lalnp with the upper edge slightly flared, if desired, in order to catch any oil that may run down on the outside of the lamp.

Having thus described my invention,

What I claim, and desire to secure by Letters latcut, is--- .1. In combination with the annular lamp L, the

socket D, sliding-rod R, vertical tube T, set-screw S,-

and base-piece B, all arranged together substantially as and for the purpose described.

2. The socket D, constructed with the circular boss b, by means of which the socket is secured to the tube or gas-fixtu're-,-and the lamp is supported above the bottom of the socket, leaving a space into which oildripping may accumulate, all as shown and described.
